Industry of powerplant:can reduce global warming?

The scientists of Utah university says that increase in carbondioxide is the main problem of rising global warming. It cannot be stabilized until the world's economy collapses or society builds the equivalent of one nuclear plant each day.

"It looks unlikely that there will be any substantial near-term departure from recently observed accleretion in carbondioxide emission rates", says Tim Garrett, an associate professer of atmospheric sciences.


Garrett's study was panned by some economists and rejected by several journals before acceptance by Climatic Change. The study which is based on the concept that physics can be used to characterize the evolution of civilization-indicates:

  • Energy conservation or efficiency doesn't really save energy,but instead spurs economic growth and acclerated energy conservation.
  • Throughout history a simple physical"constant"-an unchanging mathematical value links global energy use to the world's accumulated economic productivity, adjusted for inflation.So it isn't necessary to consider population growth and standard of living in predicting society's future energy conservation and resulting carbondioxide emissions.

It says that to stop emitting carbondioxide is impossible but it can lowered by builting a new powerplant industry.To stop global warming it can be one of the gadget.

Save energy and help to reduce pollution

All about Magniwork generator
A Zero point magnetic power generator is basically a Free Energy Generator. It uses magnets, and magnetic force to induce perpetual motion. It runs by itself, indefinitely without stopping, thus creating completely free electrical energy, which can fully power your home for free. A Perpetual motion device refers to a machine that runs perpetually i.e. indefinitely, and produces a larger amount of energy than it consumes. Thus, it produces free energy indefinitely, runs by itself, without having to need a third-party device or resource to power it.
The free energy devices have been suppressed by the corporate world, because such devices, would allow people to create their own energy for free, which would ultimately shut down the big energy corporations, because people won't need to pay anymore for electricity to fill their pockets

The magniwork free energy generator, can be efficiently used to power your home with almost zero costs on your side. Furthermore, the generator is eco-friendly and doesn't produce any harmful byproducts.
Hundreds of successful magniwork generators have been built around the world, which is a proof that this technology really works! We predict that the technology will rapidly spread, and some industry-insiders even predict that the mangiwork free energy generators will be the energy in the future. These experts estimate, that by 2020 energy companies will start implementing this technology in order to create cheaper and more environment friendly energy. Until that time comes, you can use our technology at a very reasonable set-up cost.

The Magniwork free energy generator is safe to use and operate. It doesn't produce any harmful byproducts or gases, and there isn't any hazard concerning the generator itself. Even if you have little children, they may freely walk in the close vicinity of the generator.The magniwork generator, is also a very eco-friendly solution, it doesn't pollute the environment. The generator itself isn't flammable or combustible, so it's completely safe.

Pollution control:ways to reduce global warming

Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing, transportation and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control. For pollution control we can use pollution control devices such as biofilters,vapour recovery systems,baghouses, spray tower sedimentation etc.. Though carbondioxide is vital for photosynthesis but excessive use of carbondioxide increases acidity in ocean water. So use of carbondioxide should be reduced. Pollution became popular issue after world war II after the atomic warfare. It killed many people. To stop this type of activities and growing impact of global warming we people should stop the activities that will help to rise the given problems. We are provided education about it but we don't apply it practically. It is so because human have capacity to face problems and can overcome through it. But this is different from another problems so we have to plan and implement that to reduce the problem of pollution and global warming.

Effects of pollution on different sectors.

Adverse air quality can kill many organisms including humans. Ozone pollution can cause respiratory disease, cardiovascular disease, throat inflammation, chest pain, and congestion. Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by untreated sewage in developing countries. An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrhoeal sickness every day.[25] Nearly 500 million Chinese lack access to safe drinking water.[26] 656,000 people die prematurely each year in China because of air pollution. In India, air pollution is believed to cause 527,700 fatalities a year.[27] Studies have estimated that the number of people killed annually in the US could be over 50,000.[28]
Oil spills can cause
skin irritations and rashes. Noise pollution induces hearing loss, high blood pressure, stress, and sleep disturbance. Mercury has been linked to developmental deficits in children and neurologic symptoms. Older people are majorly exposed to diseases induced by air pollution. Those with heart or lung disorders are under additional risk. Children and infants are also at serious risk. Lead and other heavy metals have been shown to cause neurological problems. Chemical and radioactive substances can cause cancer and as well as birth defects.
Pollution has been found to be present widely in the
environment. There are a number of effects of this:
Sulphur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.
Nitrogen oxides are removed from the air by rain and fertilise land which can change the species composition of ecosystems.
Soil can become infertile and unsuitable for plants. This will affect other
organisms in the food web.
Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.
Invasive species can out compete native species and reduce biodiversity. Invasive plants can contribute debris and biomolecules (allelopathy) that can alter soil and chemical compositions of an environment, often reducing native species competitiveness.
Biomagnification describes situations where toxins (such as heavy metals) may pass through trophic levels, becoming exponentially more concentrated in the process.
Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2 becomes dissolved.
The emission of
greenhouse gases leads to global warming which affects ecosystems in many ways.

Sources and causes of different pollution around surroundings


Air pollution comes from both natural and man made sources. Though globally man made pollutants from combustion, construction, mining, agriculture and warfare are increasingly significant in the air pollution equation.[8]
Motor vehicle emissions are one of the leading causes of air pollution.
[9][10][11] China, United States, Russia, Mexico, and Japan are the world leaders in air pollution emissions. Principal stationary pollution sources include chemical plants, coal-fired power plants, oil refineries,[12] petrochemical plants, nuclear waste disposal activity, incinerators, large livestock farms (dairy cows, pigs, poultry, etc.), PVC factories, metals production factories, plastics factories, and other heavy industry. Agricultural air pollution comes from contemporary practices which include clear felling and burning of natural vegetation as well as spraying of pesticides and herbicides[13]
About 400 million metric tons of
hazardous wastes are generated each year.[14] The United States alone produces about 250 million metric tons.[15] Americans constitute less than 5% of the world's population, but produce roughly 25% of the world’s CO2,[16] and generate approximately 30% of world’s waste.[17][18] In 2007, China has overtaken the United States as the world's biggest producer of CO2.[19]
In February 2007, a report by the Intergovernmental Panel on Climate Change (IPCC), representing the work of 2,500 scientists from more than 130 countries, said that humans have been the primary cause of global warming since 1950. Humans have ways to cut greenhouse gas emissions and avoid the consequences of global warming, a major climate report concluded. But in order to change the climate, the transition from fossil fuels like coal and oil needs to occur within decades, according to the final report this year from the UN's Intergovernmental Panel on Climate Change (IPCC).
[20]
Some of the more common
soil contaminants are chlorinated hydrocarbons (CFH), heavy metals (such as chromium, cadmium--found in rechargeable batteries, and lead--found in lead paint, aviation fuel and still in some countries, gasoline), MTBE, zinc, arsenic and benzene. In 2001 a series of press reports culminating in a book called Fateful Harvest unveiled a widespread practice of recycling industrial byproducts into fertilizer, resulting in the contamination of the soil with various metals. Ordinary municipal landfills are the source of many chemical substances entering the soil environment (and often groundwater), emanating from the wide variety of refuse accepted, especially substances illegally discarded there, or from pre-1970 landfills that may have been subject to little control in the U.S. or EU. There have also been some unusual releases of polychlorinated dibenzodioxins, commonly called dioxins for simplicity, such as TCDD.[21]
Pollution can also be the consequence of a natural disaster. For example,
hurricanes often involve water contamination from sewage, and petrochemical spills from ruptured boats or automobiles. Larger scale and environmental damage is not uncommon when coastal oil rigs or refineries are involved. Some sources of pollution, such as nuclear power plants or oil tankers, can produce widespread and potentially hazardous releases when accidents occur.
In the case of
noise pollution the dominant source class is the motor vehicle, producing about ninety percent of all unwanted noise worldwide.

Too much pollution from 1990 to 2007:Global warming

Washington, D.C.-Global warming pollution declined in one-third of the states since 2004, the year in which pollution levels began to peak in many states, according to a new analysis of government data released today by Environment America. States are reducing pollution in part by using cleaner energy that keeps money and jobs in the local economy. Pollution levels, however, rose in the majority of states (33) between 2004 and 2007.
"The transition to clean energy is a marathon, and we've just laced up our sneakers," said Environment America Federal Global Warming Program Director Emily Figdor. "It's time to take back control of our energy future. By harnessing the power of the wind and the sun, we can cut pollution and transition to clean energy sources that don't harm the environment, never run out, and create new, local jobs," she continued.
For decades, America's use of fossil fuels - and the global warming pollution that results - has been on the rise nationally and in states across the country. But the United States must cut its pollution by 35 percent by 2020 to be able to stop the worst effects of global warming.
Too Much Pollution: State and National Trends in Global Warming Emissions from 1990 to 2007 uses the most recent data from the U.S. Department of Energy on fossil fuel consumption by state to look at trends in carbon dioxide emissions. Environment America and our allies are releasing the report today in more than 30 states.

China secured their people's future until 2015 with insurance for industrial pollution.

China plans to introduce by 2015 a nationwide liability insurance program that will pay compensation to victims of industrial pollution.
The country's
State Environmental Protection Administration (SEPA) is working to set up the program with the China Insurance Regulatory Commission, the agency that oversees the country's insurance industry.
Pan Yue, a SEPA vice minister, told Xinhua, China's official news agency, that the plan will be tested this year with companies that produce, transport, sell, or store hazardous chemicals. "Enterprises and industries that have caused serious pollution accidents in recent years will be specially targeted," he said.
Pan noted that environmental accidents happened on average every three days in China in 2007. At present, he added, it's common for companies that cause environmental disasters to go bankrupt and for victims to go uncompensated.
The insurance scheme would allow companies involved in accidents to stay in business and enable victims to get a payout. Pan added that highly polluting firms will be charged premiums that are high enough to encourage them to improve performance. "The scheme does not mean that polluting companies can [be comfortable continuing] to pollute," Pan said.
Elut Hsu, a business development executive with Asymchem Laboratories, tells C&EN that China is adopting increasingly strict measures to crack down on industrial pollution. Asymchem is a North Carolina-based custom manufacturer of pharmaceutical ingredients with laboratories, pilot plants, and large-scale manufacturing operations in northeastern China. Hsu notes that small Chinese producers of basic pharmaceutical intermediates are "disappearing" because they can't meet tougher environmental standards.

President Barack Obama proposed a bill of free pollution permits for industries

A growing number of industries are lobbying for free pollution permits under legislation capping greenhouse-gas emissions, in a potential threat to the funding for President Barack Obama's proposed middle-class tax cut.
A range of industries, including electric utilities, auto makers, and oil and natural gas refineries, are making their case to lawmakers ahead of a vote on proposed climate legislation expected this week by the House Subcommittee on Energy and the Environment. The jockeying has intensified in recent days after a push by electric utilities to secure up to 40% of the emissions permits for free, an amount that would be proportionate to their share of U.S. carbon-dioxide emissions.
The measure by Reps. Henry Waxman (D., Calif.) and Edward Markey (D., Mass.) calls for reducing U.S. greenhouse-gas emissions roughly 20% below 2005 levels by 2020 and 83% below 2005 levels by mid-century. It is largely silent on how much companies would have to pay for pollution permits under a proposed cap-and-trade system that would allow companies to buy and sell such permits.
Mr. Obama has called for auctioning off 100% of the emission allowances and using the bulk of the revenue to fund tax credits for the middle class. His 2010 budget blueprint projects raising $645 billion from the auction of emissions permits between 2012, when the system kicks in, and 2019. A smaller portion would be devoted to research and development of low-carbon technologies. But Mr. Obama and some of his aides have signaled they are willing to compromise on giving away the pollution permits.
The bill's fate could hinge on how willing Messrs. Waxman and Markey are to give in to the demands of about a dozen Democratic committee members who want to soften the impact on their districts, which depend on coal, manufacturing, or oil and natural gas for jobs.
"There are a lot of things in the bill I need to have changed," said Rep. Gene Green (D., Texas). Mr. Green, whose district is home to the largest petrochemical complex in the world, wants Mr. Waxman to give some pollution permits to oil refiners for free. "If that's not in the bill, I can't vote for it," he said.
Refiners are lobbying to get for free 30% of the pollution permits, an amount that corresponds roughly to the share of U.S. greenhouse-gas emissions produced by transportation fuel. Without such allowances, the industry says, it will lose out to refineries in India and the Middle East that ship their product to the U.S. and don't operate under carbon caps at home.
"The electric utilities want 40%, and if they're getting 40%, the refiners say 'Why shouldn't we get 30%?"' Mr. Green said. Mr. Green said he has asked Mr. Waxman to give the refining industry a smaller share of the allowances -- roughly 5%.
Messrs. Waxman and Markey have said they intend to work out a distribution of the allowances after consulting with their colleagues, but haven't indicated specifically how the matter will be resolved. A spokeswoman for Mr. Waxman said, "We are encouraged by the progress that we are making, and the committee will continue meeting with members to discuss the legislation."
Economists say generally that consumer prices will rise regardless of whether permits are given away for free, and that giving them away for free will divert money from other purposes in the public interest, such as tax cuts for consumers. But "the politics of passing [climate legislation] in the committee are tough; it's hard to be a purist," said Chad Stone, chief economist of the Washington-based Center on Budget and Policy Priorities.
The issue is particularly thorny for the auto industry. The Obama administration has billions of public dollars at stake in turnaround efforts at Chrysler LLC and
General Motors Corp. At the same time, Mr. Obama has vowed to promulgate more aggressive fuel-economy standards for vehicles, which won't be cheap. Last summer, the Transportation Department estimated that its proposal to require auto makers to achieve fuel efficiency of 31.6 miles per gallon by 2015 would cost auto makers $46.7 billion, which the agency said would make it among the most expensive rule makings in U.S. history.
"There are a lot of interests competing for the pot of money, but I think there's a general recognition that some of the revenue…should be used to push advanced, low-carbon technologies because that's how we're going to drive the emissions reductions we need," said Alan Reuther, legislative director of the United Auto Workers.
The union, along with the Alliance of Automobile Manufacturers, is lobbying Mr. Waxman to direct that a portion of the revenue raised from the auction of carbon allowances go toward helping the industry develop more fuel-efficient vehicles to meet a federal mandate to improve new-vehicle fuel economy at least 40% by 2020.
Mr. Reuther's concerns have been echoed by Rep. John Dingell (D., Mich.), another swing vote on the panel who is leaning on Mr. Waxman to devote a portion of permit revenue to an Energy Department program that awards low-interest loans to car makers to develop advanced vehicles

Polluted bacteria can produce electricity and can clean oil

A discovery by scientists at the University of East Anglia could contribute to the development of systems that use domestic or agricultural waste to generate clean electricity.
Published recenlty by the leading scientific journal, Proceedings of the National Academy of Sciences (PNAS), the researchers have demonstrated for the first time the mechanism by which some bacteria survive by ‘breathing rocks'.
The findings could be applied to help in the development of new microbe-based technologies such as fuel cells, or ‘bio-batteries', powered by animal or human waste, and agents to clean up areas polluted by oil or uranium.
"This is an exciting advance in our understanding of bacterial processes in the Earth's sub-surfaces," said Prof David Richardson, of UEA's School of Biological Sciences, who is leading the project.
"It will also have important biotechnological impacts. There is potential for these rock-breathing bacteria to be used to clean-up environments contaminated with toxic organic pollutants such as oil or radioactive metals such as uranium. Use of these bacteria in microbial fuel-cells powered by sewerage or cow manure is also being explored."
The vast proportion of the world's habitable environments is populated by micro-organisms which, unlike humans, can survive without oxygen. Some of these micro-organisms are bacteria living deep in the Earth's subsurface and surviving by ‘breathing rocks' – especially minerals of iron.
Iron respiration is one of the most common respiratory processes in oxygen-free habitats and therefore has wide environmental significance.
Prof Richardson said: "We discovered that the bacteria can construct tiny biological wires that extend through the cell walls and allow the organism to directly contact, and conduct electrons to, a mineral. This means that the bacteria can release electrical charge from inside the cell into the mineral, much like the earth wire on a household plug."

Year of the Skeptic-2009


As scientists confirm the earth has not warmed at all in the past decade, others wonder how this could be and what it means for Copenhagen. Maybe Al Gore can Photoshop something before December.
It will be a very cold winter of discontent for the warm-mongers. The climate show-and-tell in Copenhagen next month will be nothing more than a meaningless carbon-emitting jaunt, unable to decide just whom to blame or how to divvy up the profitable spoils of climate change hysteria.
The collapse of the talks coupled with the decision by Senate Majority Leader Harry Reid to put off the Kerry-Boxer cap-and-trade bill, the Senate's version of Waxman-Markey, until the spring thaw has led Oklahoma Sen. James Inhofe, the leading Republican on the Environment and Public Works Committee, to declare victory over Sen. Barbara Boxer, D-Calif., and the triumph of observable fact over junk science.
"I proudly declare 2009 as the 'Year of the Skeptic,' the year in which scientists who question the so-called global warming consensus are being heard," Inhofe said to Boxer in a Senate speech. "Until this year, any scientist, reporter or politician who dared raise even the slightest suspicion about the science behind global warming was dismissed and repeatedly mocked. A few weeks ago Britain's Hadley Centre for Climate Prediction and Research pointed out that the earth had in fact only warmed 0.07 degree Celsius from 1999 to 2008 and not by the 0.2 degree Celsius predicted by the U.N.'s Intergovernmental Panel on Climate Change.
An even more inconvenient truth, according to the British experts, is that when their figures are adjusted for two naturally occurring climate phenomena, El Nino and La Nina, the resulting temperature trend is reduced to 0.0 degree Celsius. No, that's not a typo

To add to the warm-mongers' woes, patron saint Al Gore, the man who claimed to have invented the Internet, might also have claimed the discovery of Photoshop. Dr. Roy Spencer, of the University of Alabama at Huntsville, formerly with NASA, has taken a look at the pictures used to illustrate Gore's new book, "Our Choice: A Plan To Solve the Climate Crisis."
Gore Photoshopped NASA imagery of the earth for the fold-out cover photo, adding four hurricanes at once, including one spinning in the wrong direction next to Florida and, in a physical impossibility, one on the equator next to Peru. Somewhere in the process, the island of Cuba was deleted.
